This invention relates 'to new and ueeiul improvements in safety valves for engineg; and the object in View is tolpxoduce :t simple and elieient device of this natulfe so aiA i'enged that the weak points of the 4Valve will be positioned outside of the boilei-tliereby affording means whereby, in die event of the saine becoming lnoloen off, the valve will automatically close and :retain the Water and steam Within the boiler.

The invention illustrated in tite accompanying drawings, in which l have shown :1 oentral longitudinal sectional View through the Valve apparatus oud tiunsveisoiy througho''zhe Weil o1 the boiler. Y

Reference now being lied to the details of the drawings by lette?, l designates o. shell oircumferentielly threaded as :it .ei and adapted to iit the threaded Woll of an opening in the boiler E; and e plate lll which is: held theie'to by ineens; of" the bolts C.
